본 발명은 스위치드릴럭턴스모터용 회전자의 위치검출장치에 관한 것으로, 특히 P.C.B와 광센서의 보수/유지시 그 교체작업이 용이할 수 있도록 된 스위치드릴럭턴스모터용 회전자의 위치검출장치에 관한 것이다.The present invention relates to a position detecting apparatus for a rotor for a switch drill luxton motor, and in particular, a position detecting apparatus for a rotor for a switch drill luton motor, which can be easily replaced during maintenance and maintenance of a PCB and an optical sensor. It is about.
상기 스위치드릴럭턴스모터와 P.C.B(전자구동회로)간에는 상호간의 입력신호가 있어야 하는 바, P.C.B에서 모터로는 전원이 공급됨과 더불어 모터에서는 P.C.B에 고정자의 고정자극과 회전자의 회전자극이 이루는 각도 즉, 회전자의 위치를 입력하여 구동이 이루어지게 된다.Between the switch drill lux motor and the PCB (electronic drive circuit) should have an input signal between the bar, the power is supplied from the PCB to the motor and the angle of the stator stator and the rotor stimulation of the rotor to the PCB in the motor That is, driving is performed by inputting the position of the rotor.
이러한 회전자의 위치를 감지하는 센서는, 홀센서(HALL SENSOR)와 엔코더(ENCODER) 및 포토-인터럽트(PHOTO-INTERRUPTER;광센서) 등이 사용되는 바, 본 발명에서는 광센서를 이용하여 회전자의 위치를 감지하도록 된 것에 관한 것이다.The sensor for detecting the position of the rotor, such as a Hall sensor (HALL SENSOR), encoder (ENCODER) and photo-interrupt (PHOTO-INTERRUPTER (optical sensor), etc. are used, in the present invention, the rotor using an optical sensor To detect the position of.
종래 이와 같은 스위치드릴럭턴스모터는 도 1 및 도 2에 도시된 것과 같이, 원판형상의 받침판(10)에 나사를 매개로 하우징(20)이 고정되고, 이 받침판(10)과 하우징(20)에 회전축(30)이 베어링(40)을 매개로 회동가능하게 설치됨과 더불어, 상기 하우징(20)에 고정된 고정자(50)의 내주면에 상기 회전축(30)과 일체로 고정되어 회전되는 회전자(60)가 설치되는 한편, 상기 하우징(20)의 안쪽 측벽과 회전축(30)에 회전자의 위치를 검출할 수 있도록 위치검출장치(70)가 설치되어 있다.As shown in FIGS. 1 and 2, the switch drill luxton motor of the related art has a housing 20 fixed to a disc-shaped support plate 10 by a screw, and the support plate 10 and the housing 20. The rotor 30 is rotatably installed on the inner side of the stator 50 fixed to the housing 20 while the rotating shaft 30 is rotatably installed through the bearing 40. On the other hand, the position detecting device 70 is installed on the inner sidewall of the housing 20 and the rotation shaft 30 so as to detect the position of the rotor.
여기서 상기 위치검출장치(70)는, 상기 회전축(30)에 끼워져 하우징(20)의 안쪽 측벽과 밀착되도록 P.C.B(71)가 설치되고, 이 P.C.B(71)의 중심위치에서 일정거리의 반경에 서로 소정각도를 두고 ㄷ자형상의 센싱부(72a)를 갖춘 광센서(72)가 설치되며, 상기 회전축(30)과 나사 체결되어 일체로 회전되도록 고정부재(73)가 설치됨과 더불어, 이 고정부재(73)의 측벽에 나사에 의해 고정됨과 더불어 각각 일정각도를 두고 배치되어 직각으로 절곡된 절곡부(74a)가 상기 광센서(72)의 센싱부(72a)에 회전되면서 배치될 수 있도록 센서디스크(74)가 설치되어 있다.Here, the position detection device 70, the PCB 71 is installed so as to be in close contact with the inner side wall of the housing 20 is fitted to the rotating shaft 30, each other at a radius of a certain distance from the center position of the PCB 71 An optical sensor 72 having a C-shaped sensing unit 72a is installed at a predetermined angle, and a fixing member 73 is installed to be integrally rotated by being screwed with the rotation shaft 30 and the fixing member ( It is fixed by a screw on the side wall of the 73 and arranged at a predetermined angle, respectively, the bent portion (74a) is bent at a right angle to the sensor disk (Rotary) to be disposed while rotating to the sensing unit (72a) of the optical sensor 72 ( 74) is installed.
미설명부호 21은 하우징(20)의 원주면에 일정각도로 형성된 환기구이다.Reference numeral 21 is a vent formed at a predetermined angle on the circumferential surface of the housing 20.
따라서 상기 위치검출장치(70)의 P.C.B(71)에 전원이 공급됨과 더불어 상기 회전자(60)의 위치가 회전축(30)과 고정부재(73) 및 센서디스크(74)를 매개로 광센서(72)가 감지되어 P.C.B(71)에 입력되면 상기 회전자(60)가 회동하면서 회전축(30)을 돌려주게 된다.Therefore, power is supplied to the PCB 71 of the position detecting device 70 and the position of the rotor 60 is controlled by the optical sensor via the rotating shaft 30, the fixing member 73, and the sensor disk 74. When 72 is detected and input to the PCB 71, the rotor 60 rotates to rotate the rotation shaft 30.
즉 상기 회전자(60)의 위치를 나타내는 센서디스크(74)의 절곡부(74a)가 상기 P.C.B(71)에 설치된 다수개의 광센서(72)에 형성된 센싱부(72a)에 위치됨으로써 회전자(60)의 위치를 감지하게 된다.That is, the bent portion 74a of the sensor disk 74 indicating the position of the rotor 60 is located in the sensing unit 72a formed in the plurality of optical sensors 72 installed on the PCB 71 so that the rotor ( 60) will be detected.
그러나 이러한 스위치드릴럭턴스모터용 회전자의 위치검출장치는, 상기 P.C.B(71)나 광센서(72)가 고장이 난 경우 보수작업하기 위해서 상기 받침판(10)과 하우징(20)의 체결나사를 풀은 다음, 하우징(20)의 측벽에 P.C.B(71)를 고정시키기 위해 체결한 나사를 풀은 뒤, 상기 하우징(20)을 회전축(30)으로부터 분리시킨다. 이후 상기 광센서(72)가 설치된 P.C.B(71)를 회전축(30)에서 뽑아내어 보수/유지작업을 한 다음 재차 조립하게 되기 때문에 P.C.B(71)와 광센서(72)의 보수/유지에 따르는 작업이 번거롭고 작업시간이 많이 소요되는 결점이 있었다.However, such a position detection device of the rotor for the switch drill lug motor, the fastening screw of the support plate 10 and the housing 20 for maintenance work when the PCB 71 or the optical sensor 72 is broken. Next, after loosening the screw fastened to fix the PCB 71 on the side wall of the housing 20, the housing 20 is separated from the rotation shaft 30. After the PCB 71, the optical sensor 72 is installed is pulled out of the rotating shaft 30 to perform the maintenance / maintenance work and then reassembled work in accordance with the maintenance / maintenance of the PCB 71 and the optical sensor 72 This was a cumbersome and time consuming drawback.
또한 절곡형 회전판의 경우 청소기용 모타와 같이 고속 회전하는 경우 원심력에 의해 절곡부(74a)가 휘어지는 결점이 있었다.In addition, in the case of the bent rotary plate, the bent portion 74a is bent due to the centrifugal force when rotating at a high speed such as a cleaner motor.
이에 본 발명은 상기와 같은 제반결점을 해결하기 위해 안출된 것으로, 회전자의 위치를 나타내도록 회전축에 고정부재를 매개로 설치된 센서디스크의 돌출부 센싱부가 하우징의 원통부에 형성된 환기구에 P.C.B고정부재와 P.C.B를 매개로 연결 설치된 광센서에 의해 위치를 검출할 수 있도록 되어, P.C.B와 광센서의 보수/유지시 그 작업이 용이할 수 있도록 된 스위치드릴럭턴스모터용 회전자의 위치검출장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and the PCB fixing member and the ventilation hole formed in the cylindrical portion of the housing of the sensor sensing portion of the sensor disk installed via the fixing member on the rotating shaft to indicate the position of the rotor and The position sensor can be detected by the optical sensor installed through the PCB, and the position detection device of the rotor for the switch drill luton motor can be easily operated when repairing and maintaining the PCB and the optical sensor. The purpose is.
